我第一次使用docx4j Java庫，並且在找到一個很好的參考時遇到了一些困難。我需要啓動的是一個簡單的Java類，以只讀模式強制保護Word文檔。我有很多，我可以讀取保護模式並設置它。但是，在保存Word文檔時，更改不會寫入Word文檔。如何用docx4j保存更改Java庫到word文檔
public class Doc4JPOC {
public static void main(String[] args) {
String docName = "/Users/petervannes/Desktop/Unprotected document.docx";
// String docName = "/Users/petervannes/Desktop/Protected document.docx" ;
Doc4JPOC d4j = new Doc4JPOC();
d4j.isProtected(docName);
d4j.protect(docName);
d4j.isProtected(docName);
}
private void protect(String filename) {
try {
WordprocessingMLPackage wordMLPackage = Docx4J.load(new java.io.File(filename));
MainDocumentPart mdp = wordMLPackage.getMainDocumentPart();
Relationship rs = mdp.getRelationshipsPart().getRelationshipByType(Namespaces.SETTINGS);
DocumentSettingsPart dsp = (DocumentSettingsPart) mdp.getRelationshipsPart().getPart(rs);
// Update settings.xml
List<Object> nodes = dsp.getJAXBNodesViaXPath("//w:documentProtection", true);
for (Object obj : nodes) {
CTDocProtect cdtP = ((CTDocProtect) obj);
cdtP.setEnforcement(Boolean.TRUE);
cdtP.setEdit(STDocProtect.READ_ONLY);
}
// Write updated settings.xml to document
wordMLPackage.addTargetPart(dsp);
// wordMLPackage.save(new java.io.File(filename));
Docx4J.save(wordMLPackage, new java.io.File(filename), 0);
System.out.println("Protected document " + filename) ;
} catch (Docx4JException ex) {
Logger.getLogger(Doc4JPOC.class.getName()).log(Level.SEVERE, null, ex);
} catch (JAXBException jex) {
Logger.getLogger(Doc4JPOC.class.getName()).log(Level.SEVERE, null, jex);
}
}
private void isProtected(String filename) {
Boolean isProtectionEnforced = false;
STDocProtect editMode = STDocProtect.NONE;
try {
WordprocessingMLPackage wordMLPackage = Docx4J.load(new java.io.File(filename));
MainDocumentPart mdp = wordMLPackage.getMainDocumentPart();
Relationship rs = mdp.getRelationshipsPart().getRelationshipByType(Namespaces.SETTINGS);
DocumentSettingsPart dsp = (DocumentSettingsPart) mdp.getRelationshipsPart().getPart(rs);
System.out.println("Partname : " + dsp.getPartName());
List<Object> nodes = dsp.getJAXBNodesViaXPath("//w:documentProtection", true);
for (Object obj : nodes) {
CTDocProtect cdtP = ((CTDocProtect) obj);
isProtectionEnforced = cdtP.isEnforcement();
editMode = cdtP.getEdit();
System.out.println("Enforced: " + cdtP.isEnforcement());
System.out.println("Edit: " + cdtP.getEdit());
}
if (isProtectionEnforced) {
System.out.println("Protection is enabled , protection mode is " + editMode.toString());
} else {
System.out.println("Protection is disabled");
}
} catch (Docx4JException ex) {
Logger.getLogger(Doc4JPOC.class.getName()).log(Level.SEVERE, null, ex);
} catch (JAXBException jex) {
Logger.getLogger(Doc4JPOC.class.getName()).log(Level.SEVERE, null, jex);
}
}
}
當執行此類時，我得到以下輸出;
Partname : /word/settings.xml
Protection is disabled
Protected document /Users/petervannes/Desktop/Unprotected document.docx
Partname : /word/settings.xml
Protection is disabled
所以我懷疑我不是在保護方法正確地更新WordprocessingMLPackage或DocumentSettingsPart，但目前都沒有任何線索的地方出了問題。
